Holmsen, Kyncl and Valculescu recently conjectured that if a finite set X with ln points in Rd that is colored by m different colors can be partitioned into n subsets of l points each, such that each subset contains points of at least d different colors, then there exists such a partition of X with the additional property that the convex hulls of the n subsets are pairwise disjoint. We prove a continuous analogue of this conjecture, generalized so that each subset contains points of at least c different colors, where we also allow c to be greater than d. Furthermore, we give lower bounds on the fraction of the points each of the subsets contains from c different colors. For example, when n⩾ 2, d⩾ 2, c⩾ d with m⩾ n (c− d)+ d are integers, and µ1,..., µm are m positive finite absolutely continuous measures on Rd, we prove that there exists a partition of Rd into n convex pieces which equiparts the measures µ1,..., µd− 1, and in addition every piece of the partition has positive measure with respect to at least c of the measures µ1,..., µm.
